<p>Thanks for the positive comments and sorry for the delay, I was on vacation.</p>
<p>@Rumi: Yes, you can use SC 3.2 11/09 (Update 3) as well. But I would recommend to use Solaris 10 05/09 (Update 7) because of CR 6888193, as mentioned in the white paper. Once a fix is available, you can use S10 Update 8 as well, but until then the iSCSI initiator part would not work as described in the paper.</p>
<p>@Gabor: I don't have a better recommendation in order to prevent the pm_tick delays. Since the messages flood syslog without my recommended change to syslog.conf, that was the only reason that made my system panic/non-responsive. Of course you have to restart syslog after the change. But I guess it also depends on the host system and how busy the guests drive the CPU (and thus add delays for the guests). In the M10 case it is a dual core cpu with hardware virtualization feature turned on in the BIOS.</p>

<p>Nice writing, thanks.<br/>
I experiment with a similar configuration but using Linux (Gentoo) as a host OS with VirtualBox. (And tried VMWare Server and Workstation above Linux and Win XP, too.)<br/>
All of this works fine except one thing: Sometimes the pm_tick delay gets too high, and one of the cluster nodes panicks. Your syslog.conf modification does not help to prevent this.<br/>
Google gives some clues, how to solve this, but found no good solution. The best clue I've found was trimming the cluster transport timings:<br/>
scconf -w heartbeat_timeout=60000<br/>
scconf -w heartbeat_quantum=10000<br/>
This notably reduces the possibility of the panic, but does not eliminate them. (Further trimming does not make more advance.)</p>
<p>Could you suggest something to prevent this pm_tick delay panics?</p>

<p>Hi Thorsten,</p>
<p>This looks fantastic. Can I use Sun Cluster3.2 Update 3 with this configuration rather than Update 2?</p>
<p>Kind regards</p>

<p>Es handelt sich um ein Java Applet. Leider war es bisher nicht m&ouml;glich die Freigabe zu bekommen das Teil zum download herauszugeben :-(</p>
<p>Ich h&auml;tte auch gerne ein allgemein verf&uuml;gbares Demo, so das jedermann Cluster einfach demonstrieren kann. F&uuml;r gute Ideen &uuml;ber ein visuelles Demo bin ich offen und dankbar.</p>
<p>Was ich habe (und verf&uuml;gbar machen k&ouml;nnte) ist ein auf CLI Ebene MySQL (oder auch PostgreSQL) Client Skript, das u.a. das Datum zyklisch in eine Tabelle schreibt, entsprechend kann man dann bei und nach Failover die Tabelle auslesen und nachvollziehen das nichts verloren ging. Ist aber eben leider nicht graphisch. Wenn ich nach meinem Urlaub etwas Zeit finde, pack ich das mal in einen Blog.</p>
<p>Danke f&uuml;r das Feedback.</p>
<p>- Thorsten</p>

<p>Ich habe den Vortrag gestern auf der FrOSCon gesehen und fand ihn gut. Von daneben stehen keine Spur. Allerdings bin ich mit SunCluster (seit PDB 1.3), Solaris und Sun-Hardware schon schwer vorbelastet :-)</p>
<p>Gibt es eigentlich das Javascript-Demo f&uuml;r den Client wo zum runter laden?</p>

<p>Great news! Now we need a solution (SRA), for VMWARE DRR solution (SRM). </p>

The second phase will include the source for SC Geo Edition and the third phase will then include the source for the Sun Cluster framework. It will at least take until end of 2008 to reach this third phase. -- Thorstenhttps://blogs.oracle.com/TF/entry/solaris_cluster_express_07_07#comment-1185761793000Re: Solaris Cluster Express 07/07 is available!Leon Koll2007-07-30T02:16:33+00:002007-07-30T02:16:33+00:00Sounds great! Is it possible to bowse the Solaris Cluster Express source tree ?
Thank you,

And I hope customers express their need to Oracle as well.
RAC 10gR2 64 &amp; 32-bit is certified with Sun Cluster 3.1 on Solaris 10 x86-64 today.
Sun does already support it also on Sun Cluster 3.2, and are in the process to get it certified with Oracle as soon as possible.
